Can anybody explain some good use cases of implicit return? When I was doing a project in CoffeeScript last year (the only time I've used it), I found myself just using the return keyword explicitly because it was more readable, and I never ran into the issue the article talks about where it can be bad to accidentally return something from a function that should return null/undefined.

When would implicit return make code better? Maybe I'm answering my own question, but I can see them being more readable to somebody coming from a Haskell or LISP background than to somebody like me who has worked mostly in C, Java, and Python.
